You are trying to upload the APNs (MDM_ZOHO_Corporation_Certificate.pem) file, that you have downloaded from the Apple website in the Mobile Device Manager Plus server and you get an error message "Provide the latest Vendor-signed CSR certificate!"
While creating APNs certificate, you will have to download the Vendor Signed CSR from the Mobile Device Manager Plus server and upload it in the Apple website to download MDM_ZOHO_Corporation_Certificate.pem. After downloading the MDM_ZOHO_Corporation_Certificate.pem file, it needs to be uploaded in the Mobile Device Manager Plus server. If the Vendor Signed CSR does not match with the downloaded APNs certificate, then you might get this error.
You need to verify if the most recently downloaded "Vendor Signed CSR" is uploaded in the Apple Push Notification portal to generate APNs.
In case you have downloaded the "Vendor Signed CSR" more than once, follow the steps mentioned below:
Note: If you have more than one Vendor Signed CSR, it is recommended to delete them all and restart the process, so that you can download a fresh Vendor Signed CSR and upload it in the Apple Portal to generate the appropriate APNs certificate.
